-### Auto-Generate An OpenAPI V3 Specification From Your Express.js App
-
-Version 1.5.0 introduced experimental support for auto-generating an OpenAPI specification from your Express app upon every deployment, then adding them to the `outputs` of your app.
-
-This works by attempting to run your application on each deployment and extracting the routes you've defined in your Express app.
-
-Currently, this feature is disabled by default, since it's experimental. To enable it, add `openApi: true` to your `serverless.yml` and ensure you are using the latest version of the Express coponent (>= 1.1.0).
-
-Given a lot of things can happen in your application upon starting it up, this does not work consistently. For example, your environment variables will NOT be available during this process, which could cause your app not to initialize.
-
-If it runs into an error trying to start your application, it will try its best to pass through useful errors to you so you can address what's blocking it from working.  You can see these by running `serverless deploy --debug`
-
-Overall, an OpenAPI specification generated by default is very powerful. This means you don't have to maintain that manually since it auto-updates on every deployment. (That's what serverless is all about!)
-
-We will be adding many interesting features built on this. Extracting your endpoints and putting them into a common format was merely the first step...
